Description

Technical Field

[0001] This application relates to the field of air pumps, and more particularly to a portable vehicle-mounted air pump. Background Art

[0002] An air pump, also known as an "air compressor", is a device that removes air from or adds air to a closed space. Air pumps are mainly divided into electric air pumps, manual air pumps, and foot-operated air pumps. Electric air pumps use electricity as the power source to continuously compress air to generate air pressure. They are mainly used for inflating, sewage treatment, electroplating air supply, biogas digester aeration, tunnel ventilation, etc. A vehicle-mounted air pump is a small air pump that can be conveniently used to replenish air in a car tire when the tire pressure is insufficient. Since it needs to be carried around with the vehicle, a small air pump is generally used.

[0003] Working principle of the vehicle-mounted air pump: When the motor runs and air is being drawn in, the valve of the connector is pushed open by the atmospheric pressure, and the air enters the air cylinder. When inflating the tire, the valve is closed by the air pressure in the air cylinder, and the air then enters the tire. Generally, an electric inflator is used, so the inflator usually comes with a power cord, and an air hose is used to inflate the tire.

[0004] Since the above-mentioned vehicle-mounted air pump needs to be powered by an external power source, in order to use it better, it needs to have a long power cord. However, a long power cord is prone to tangling. Therefore, a long air hose can also be used to output air to solve this problem. However, an overly long air hose will affect the portability of the vehicle-mounted air pump. To solve this problem, the air hose can be disassembled and stored separately. However, storing the vehicle-mounted air pump in two parts requires installation during use, and on the other hand, it is easy to forget or lose some parts when stored separately. Summary of the Utility Model

[0005] In order to increase the inflation distance of the vehicle-mounted air pump while ensuring portability, this application provides a portable vehicle-mounted air pump.

[0006] The portable vehicle-mounted air pump provided by this application adopts the following technical solutions:

[0007] A portable vehicle-mounted air pump comprises an air pump body, a power supply line and an air outlet component, the air pump body is provided with an air outlet hole, the air outlet component is installed on the air outlet hole of the air pump body, the air outlet component comprises an air outlet box, an air outlet hose and an air nozzle adapted for automobile tires, the air outlet box comprises an inner tube and an outer box, the inner tube and the outer box are slidably installed, the inner hollow interior of the inner tube is set as an air outlet cavity, the air outlet box is installed on the air pump body and is connected with the air outlet cavity through the air outlet hole, the outer peripheral wall of the inner tube is provided with a connecting pipe connected to the air outlet cavity, one end of the air outlet hose is installed on the connecting pipe, and the other end is provided with the air nozzle, the air outlet hose is wrapped around the inner tube, and the outer box slides relative to the inner tube and covers or exposes the air outlet hose.

[0008] By adopting the above technical scheme, the air outlet hose is stored in the air outlet box, and the air outlet hose is restricted on the inner tube by the outer box. The air outlet hose is wrapped and stored in a manner so that it will not be scattered all over the floor and affect the placement of the air pump. The air pump is also more portable when it is taken for use. The inner tube and the outer box are slidably matched with each other. The inner tube can be easily exposed by sliding, and then the air outlet hose can be conveniently removed from the inner tube or wrapped around the inner tube. At the same time, the outer box can wrap the inner tube by sliding, which can restrict the air outlet hose from falling out by itself.

[0009] Optionally, the inner tube is installed on the air pump body, a sliding mounting hole is opened at the end of the inner tube, a sliding column is provided at the bottom of the outer box, the sliding column is slidably installed in the sliding mounting hole, and a winding groove for accommodating the air outlet hose is formed between the outer box and the inner tube.

[0010] By adopting the above technical solution, the inner tube is fixed on the air pump body, and the outer box slides relative to the inner tube. The outer box mainly plays a role in limiting the air outlet hose from escaping from the entangled state.

[0011] Optionally, the outer box is installed on the air pump body, one end of the outer box is open, a sliding tube is provided at the bottom of the outer box, the inner tube is slidably installed on the sliding tube, the air outlet cavity is formed between the inner tube and the sliding tube, and a winding groove for accommodating the air outlet hose is formed between the outer box and the inner tube, and the space of the winding groove can allow the air outlet hose to be wound in multiple layers.

[0012] By adopting the above technical solution, the outer box is fixed on the air pump body, and the inner tube slides in the outer box, thereby exposing the air hose, making it convenient to wind and unwind the air outlet hose. At the same time, the space in the winding groove can be used to wind multiple layers of air outlet hoses, thereby reducing the length of the air outlet box and increasing the width of the air outlet box. The space occupied by the air pump when placed is more controllable and more portable.

[0013] Optionally, the connecting pipe is arranged on the outer wall of the inner pipe at the end far from the bottom of the outer box, and the distance between the connecting pipe and the inner wall of the outer box is smaller than the diameter of the air outlet hose.

[0014] By adopting the above technical solution, the presence of the connecting pipe not only provides installation for the air outlet hose, but also restricts the air outlet hose from slipping out of the winding groove. At the same time, the connecting pipe is located at the end of the inner pipe far from the bottom of the outer box, so that the air outlet of the connecting pipe is not easily restricted by the sliding pipe, keeping the air outlet smooth and not affected by the position of the inner pipe.

[0015] Optionally, a limiting convex ring is arranged at the end of the inner pipe close to the bottom of the outer box, and the distance between the limiting convex ring and the inner wall of the outer box is smaller than the diameter of the air outlet hose.

[0016] By adopting the above technical solution, the air outlet hose is restricted by the limiting convex ring, so that when the inner pipe slides out of the outer box, the air outlet hose is smoothly taken out of the winding groove and is not easily taken out into the outer box.

[0017] Optionally, the connecting pipe is arranged to extend circumferentially around the inner pipe.

[0018] By adopting the above technical solution, the bending degree of the end of the air outlet hose connected to the connecting pipe is relatively low when the air outlet hose is wound around the inner pipe, which is convenient for winding the air outlet hose, and the air outlet hose is not easily bent and damaged.

[0019] Optionally, the air pump main body is provided with a connecting convex column, the air outlet hole is coaxially opened on the connecting convex column, the air outlet box is threadedly installed on the connecting convex column, and the air outlet cavity is communicated with the air outlet hole.

[0020] By adopting the above technical solution, the air outlet box is connected to the connecting convex column by a threaded installation method, so that the entire air outlet assembly can be removed, further improving the portability of the air pump.

[0021] Optionally, a wire protrusion is arranged on the side wall of the air pump main body for installing the air outlet assembly, the power supply wire is located on the wire protrusion, and the wire protrusion and the air outlet box are arranged at intervals and form a winding gap for the power supply wire to wind through.

[0022] By adopting the above technical solution, the presence of the wire protrusion enables the power supply wire to be wound and stored, and the cooperation between the wire protrusion and the air outlet box enables the power supply wire to be wound more firmly, making better use of the air outlet box.

[0023] In summary, the air outlet hose is stored in the air outlet box, and the air outlet hose is restricted on the inner tube by the outer box. In the way of winding and storing, the air outlet hose will not be scattered on the ground, which affects the placement of the air pump. When taking the air pump for use, it is more portable. The inner tube and the outer box adopt a mutually sliding matching method. Through the sliding method, the inner tube can be conveniently exposed, and then the air outlet hose can be conveniently removed from the inner tube or wound around the inner tube. At the same time, the outer box wraps the inner tube by sliding, which can prevent the air outlet hose from slipping out by itself. Brief Description of the Drawings

Detailed Description of the Embodiment

[0029] The following will further describe the present application in detail Figures 1-4 with reference to the attached drawings.

[0030] The embodiment of the present application discloses a portable vehicle-mounted air pump.

[0031] Refer to Figure 1 and Figure 2, A portable vehicle inflator, comprising an air pump main body 1, a power supply wire 2 and an air outlet assembly 3. The air pump main body 1 is horizontally placed, and a base 4 is provided on the lower side of the air pump main body 1 to support the air pump main body 1. One end of the air pump main body 1 intakes air, and on the upper side wall of the air pump main body 1 away from the base 4, connecting studs 11 and wire protrusions 12 are arranged at intervals along the length direction of the air pump main body 1. The power supply wire 2 extends from the side of the wire protrusion 12 away from the connecting stud 11. The connecting stud 11 is vertically arranged, and an air outlet hole 13 is coaxially opened at one end of the connecting stud 11 away from the air pump main body 1. The air outlet assembly 3 is detachably installed on the connecting stud 11.

[0032] Referring to Figure 2 and Figure 3 , the air outlet assembly 3 includes an air outlet box 31, an air outlet hose 32 and a nozzle 33 adapted to an automobile tire. The air outlet box 31 includes an inner tube 312 and an outer box 311. The inner tube 312 is slidably fitted and installed with the outer box 311. There are two installation methods for the inner tube 312 and the outer box 311. In one implementation, the outer box 311 is threadedly connected to the connecting stud 11, and the inner tube 312 is slidably installed inside the outer box 311.

[0033] Specifically, the outer box 311 is a cylindrical pipe fitting with one end open and one end closed. A sliding tube 3111 protrudes coaxially from the inner bottom wall of the outer box 311. The hole in the sliding tube 3111 also penetrates the bottom wall of the outer box 311, so that the connecting stud 11 can be screwed into the sliding tube 3111. The inner tube 312 is slidably installed on the sliding tube 3111. Specifically, the inner tube 312 is a pipe fitting with one end open and one end closed by a cover 3122. The inner tube 312 includes a tube body 3121 and a cover 3122. The hole at the open end of the inner tube 312 is set as a sliding hole 3123. The sliding tube 3111 enters the inside of the inner tube 312 through the sliding hole 3123. At the same time, the diameter of the sliding hole 3123 is smaller than the inner diameter of the inner tube 312. A limiting ring 34 is threadedly installed at one end of the sliding tube 3111 located inside the inner tube 312, so as to limit the inner tube 312 from detaching from the sliding tube 3111. The cover 3122 is threadedly installed at one end of the tube body 3121 to form the closed end of the inner tube 312. At the same time, the cover 3122 also limits the depth of the inner tube 312 sliding into the outer box 311. In order to improve the sealing performance between the inner tube 312 and the sliding tube 3111, a rubber sealing layer is provided on the hole wall of the sliding hole 3123 and the side wall of the limiting ring 34 facing the bottom of the outer box 311.

[0034] The space between the inner tube 312 and the sliding tube 3111 forms an air outlet cavity 5. A connecting tube 36 communicating with the air outlet cavity 5 is provided on the outer peripheral wall of the inner tube 312. The connecting tube 36 is provided on the outer wall of the end of the inner tube 312 away from the bottom of the outer box 311. In this embodiment, the connecting tube 36 is provided on the outer wall of the cover body 3122, and the connecting tube 36 extends circumferentially around the inner tube 312. At the same time, an opening is provided at the end of the cover body 3122 located inside the tube body 3121 and communicates with the air outlet cavity 5, thereby connecting the air outlet cavity 5 and the connecting tube 36.

The space of the winding groove 6 can accommodate the air outlet hose 32 to be wound in multiple layers. At the same time, the distance between the connecting tube 36 and the inner wall of the outer box 311 is smaller than the diameter of the air outlet hose 32. When the cover body 3122 abuts against the sliding tube 3111, a part of the connecting tube 36 enters the inside of the outer box 311.

[0035] At the same time, a limiting convex ring 7 is provided at the end of the inner tube 312 close to the bottom of the outer box 311, and the distance between the limiting convex ring 7 and the inner wall of the outer box 311 is smaller than the diameter of the air outlet hose 32.

[0036] The wire protrusion 12 and the air outlet box 31 are arranged at intervals and form a winding gap 8 for the power supply wire 2 to wind through.

[0037] Refer to Figure 4 In another embodiment, the inner tube 312 is threadedly connected to the connecting convex column 11, and the outer box 311 is slidably installed on the inner tube 312. Specifically, one end of the inner tube 312 is open and threadedly installed on the connecting convex column 11.

A winding groove 6 for accommodating the air outlet hose 32 is formed between the outer box 311 and the inner tube 312. In this embodiment, a limiting convex ring 7 is provided at the lower end of the inner tube 312. At this time, the diameter of the limiting convex ring 7 is larger than the inner diameter of the outer box 311. After the outer box 311 slides downward, it abuts against the limiting convex ring 7. At the same time, an exposed notch 94 is provided at one end of the outer box 311 facing the limiting convex ring 7, so that the end of the air outlet hose 32 can extend out of the exposed notch 94 for fixation.

[0038] The implementation principle of a portable vehicle-mounted air pump in an embodiment of the present application is as follows: After the inner tube 312 and the outer box 311 slide relative to each other, the air outlet hose 32 is exposed. After the air outlet hose 32 is unscrewed, inflation can be carried out. When not in use, the air outlet hose 32 is wound around the inner tube 312 and then the inner tube 312 is slid into the inside of the outer box 311, and the air outlet hose 32 on the inner tube 312 is restricted by the outer box 311.

[0039] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
